Background and Purpose : This study was to analysis effects of muscle fatigue on error of elbow joint sense. Methods : A total 19 healthy student(men = 10, women = 9) who did't have any problem of musculoskeletal system in upper extremities participated this study. we divided two groups into young group(n = 10, $19.67{\pm}.5$) and old group(n = 9, $28.56{\pm}1.5$). In order to evoke muscle fatigue of elbow flexor, we used Biodex, and participations performed concentric contraction of elbow flexor 150 numbers as well as we measured error of joint sense using by Biodex. We collected data just after, 30min, 2hour, 24hour after evoked muscle fatigue, and we finanlly acquired average value of three times measured joint sense of elbow joint. And we calculated value of percentage of error of joint sense. We analyzed collected data by repeated ANOVA, ANOVA using by SPSS ver.12.0 program. Result : This study showed that there was no significantly effects between groups and within groups, we could see that there was significantly difference among duration by each group of age, and sex(p<.05). Conclusion : The error of joint position sense presented highest value just period after evoked muscle fatigue compared after 30 min, 2 hours, 24 hours, and we can't find out interaction between duration and age and sex.

The history of occupational health in Korea s covered the era of the Republic of Korea after the Liberation from the Japanese colonialism. But the number of Korean workers exceeded about 2 millions at the times of liberation in 1945, so that it is expected that many occupational health problems inflicted Korean workers under the Japanese colonialism. The authors reviewed medical literatures, administrative documents, and other available data which were published under the colonial state, and collected things which had reference to the health status of Korean workers. The results were as follows : 1. Nutritional status of Korean workers was supposed to be inferior to that of general population, some students, and poor inhabitants in a remote mountain villages. 2. It was supposed that the constitution of Korean workers was near lower limit of average build of contemporary Koreans. 3. The accidents rate in mines was significantly high but decreasing year after year, and the most important cause of accidents was the fall of roof in the mine. The medical facilities and equipments for miners were supposed to be not sufficient in the mines and workshops. 4. Some occupational disease including silicosis, noise-induced hearing impairment, and decompression disease were known. But, overall incidence or prevalence of these diseases could not be identified. 5. On the whole, the fatalities of acute infectious diseases of Korean workers were higher than those of Japanese inhabitants in Korea and Korean inhabitants. The prevalence of pulmonary tuberculosis of Korean workers was increasing with every passing year. 6. The medical personnels and facilities were so deficient that most Korean workers were out of adequate medical use. We discussed only a part of the health status of Korean workers under the Japanese colonialism, so it would be necessary to have a better grasp of details of occupational health policy and health status in the era of afflicting.

Objectives:We examined the reliability and validity of the Korean version of Body image scale in Korean patients with breast cancer. Methods:The sample consisted of 140 breast cancer patients. The complete Korean version of the body image scale(K-BIS), self-reports, and psychiatric interviews with a psychiatrist were used. To analyze the validity, the patients completed the Hamilton Anxiety Scale(HAM-A), the Hamilton Rating Scale for Depression(HAM-D), the Self-Esteem Scale, the Social Support Scale, and the Korean version of the European Organization for Research and the Treatment of Cancer of the life questionnaire Breast Cancer Module(QLQ-BR23). To analyze the degree of discriminant validity, the patients were separated according to surgery type(Breast conserving surgery, BCS, N=48 ; Modified radical mastectomy, MRM, N=92) and time since surgery(≤3 weeks, N=58; >3 weeks, N=92). Results:Cronbach’s α was 0.918, indicating that K-BIS has adequate internal consistency and validity. Regarding convergent validity, all QLQ-BR23 symptom domains, HAM-A total scores, and HAM-D total scores was positively were correlated with the K-BIS total scores. All QLQ-BR23 function domains were negatively correlated with the K-BIS total scores, particularly those pertaining to the body image domain. Conclusions:This study shows that K-BIS is likely to be a reliable and valid measure of body image in breast cancer patients.

A self-administered, health history questionnaire prepared for epidemiological studies or routine use in a medical clinic was completed twice(with different order), and subjects were interviewed with same questions. The reliability of the responses of 45 subjects, all male college students, were tested statistically. In this setting, 45 subjects averaged 6.7 minutes to complete the questionnaire. Test-retest reliabilty of responses to the questionnaire was 0.89(by each respondent), 0.90(by each question) by agreement index and 0.54(by each respondent), 0.47(by each question) by kappa index. The study results showed a low incidence of false positive(5.8 percent) and false negative(3.9 percent) responses. By categorical classification of history contents, 'habit' was the most reliable part, and the next order was past medical history, family history, present symptoms, and past symptoms. The value of agreement and kappa index was significantly correlated. Test-retest reliability of responses to questionnaire and interview by a paramedical personnel was 0.86(by each respondet), 0.86(by each question) by agreement index, and 0.28(by each respondent), 0.27(by each question) by kappa index, which was lower than that of responses to questionnaire only. Both levels of reliability were significantly correlated. The incidence of false positive responses was 4.4 percent and false negative response was 8.9 percent.
